MAT FOR SEED-PRESSES.

SPECIFICATION' forming part of Letters Patent No. 321,258, dated June30, 1885.

Application filed May 4, 1885.

To all whom it may concern.-

Be it known that I, CHARLES H. STRUEBIG, of Milwaukee, in the county ofMilwaukee, and in the State of Wisconsin, have invented certain new anduseful Improvements in Mats for Seed-Presses, and I d'o hereby declarethat the following is a full, clear, and exact description thereof.

My invention relates to mats for oil-presses, and will be fullydescribed hereinafter.

In the drawings, Figure 1 is a vplan view of the frame upon which myimproved mats are made, showing a partly-completed mat thereon. Fig. 2is a plan view of the completed mat. Fig. 3 is a plan view of a needle,and Fig. 4 is a plan view of the compressing mechanism with apartly-finished mat therein.

A A A2 A5, Snc., are needles, which in the rst stage of the constructionof a mat are clamped between plates B B at their center, the latterplate carrying lugs b, each pair of which separates each needle from itsneighbor, the plates Bl B being held together by screw -clamps C. Afterthese needles have been placed in the clamps the operators may work onthe frame at once, each beginning at the plates B B and working outward,as follows: The rope used is of hair, and the end of each rope isspliced about an outer needle, and then, starting at A, the rope a ispassed under needles A A2, over needles A3 and A4, under needles A5 A5,over A7 and A5, under A A10, over A11 A12, under ,A13 A14, and over A15,back under A11, over A13 and A12, under" A11 and A1", and so on untilthe border is reached, and then the rope a, starting at A15, is passedover A15, under A14, over A15, under A11, and so on, passing under A andback over and under alternate needles until it reaches A15 again, whereit is spliced. In this last row the rope is twisted upon itself with aneedle between each twist.

The lower half of Fig. l gives the appearance of the mat at thislast-described stage with the lines of rope parted from each other,while the upper portion gives the appearance of the same after the lineshave been pressed together by hand, or,in other words, worked close.77

The next stage in the manufacture consists in removing plate B andlifting the half-fin- (No model.)

ished mat from it and then placing it on frame D. i The frame D isrectangular, and has lugs d at or near each corner to receivescrewshafts E, and a bar, F, extends across one end of the frame, and isprovided with pins or lugs f, similar to those on plate B, while anotherbar, F, having screw-threaded openings through its ends, is arrangedparallel with bar F, and a shaft, E, is passed through each of theseopenings. Except that bar F travels on screw-shaft E, it is just likebar F, having a row of lugs or pins arranged along its entire length,and when the mat is laid on the frame the ends of the needles lie witheach pair separated by a lug or pin. Now, by means of a crank on eachshaft E, the two shafts are turned and the bar F screwed up toward thebar'F, and the two sections of the mat are compressed into one compactmass. Then, by means of the needles A A A2, Ste., each of which has aneye at each end to receive the tapered end of a rope, G, the body ofwhich is of about the diameter of the needles, the rope G, beginning inthe middle, 1s carried through the fabric to take the place of theneedles, and after being drawn tightly is interlaced at the terminalcorners of the mat, and the result is a complete mat, H. It will benoted that the surface of the mat is raised, as ath, on each edge of themat. This is to give additional strength to the structure, and isproduced by increasing the diameter of the rope of each section, asshown in the lower half of Fig. 1.

When the mat is in the press, the raised portions h lie outside of theedges of the compressing-plate. l

Mats made according to my invention present a practically even and levelsurface to the press, and are very strong and durable. The ropes orcords in the sections of the mat are twisted in opposite directions tokeep the mat from warping in process of construction.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. A mat for presses, Sto., consisting of aseries of longitudinal cordsinterlaced about a series of transverse cords, then compressed and boundtogether by the transverse cords, as set forth.

2. In a mat, the combination of the trans- I verse cords with thelongitudinal cords, the latter interlaced with the former, and havingincreased diameters toward their outer ends.

3. A mat formed with side ridges and intermediate level surface, asdescribed.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
